COAL-WASH ER.

No. s4e,14.1.

Specification of Letters Patent.

Patented March 5, 1907.

To all whom it may concern.-

Be it known that I, J OSEPH RAPP, a citizen of the United States of America, residing in Oollinsville, in the county of Madison and State of Illinois, have invented certain new and useful Improvements in Ooal-W'ashers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to improved means for operating the conveyors through the medium of which the refuse or foreign matter present with coal is delivered from coalwashers as it is discharged from the jig in which the coal is washed, a prime object of the invention being to provide for the operation of the refuse-conveyer only during the periods of delivery of coal into the jig, thereby avoiding unnecessary wear and tear on the machinery of the washer.

Figure I is a top or plan view of a coalwasher having my improvement embodied therein. Fig. II is a vertical longitudinal section taken on line II II, Fig. I. Fig. III is an enlarged vertical cross-section taken on line III III, Fig. I, through the eccentric members associated with the driving-wheel of the conveyer-operating mechanism. Fig. IV is a vertical section taken on line IV IV, Fig. I, through the driving-Wheel of the conveyer-operating mechanism and the eccentric members associated with said Wheel.

1 designates the Washing-tank of a coalwasher, at the discharge end of which is a discharge-runway 2, onto which the coal is discharged as it is washed. 3 is a coal-delivery chute leading -to the receiving end of the washer.

4 designates a jig having the usual inclined perforated bottom 5 and containing the outlet 6 for the discharge of refuse, such as slate. The jig is supported for rise-and-fall motion within the washing-tank by hangers 7, loosely connected to shafts 8, applied to the jig, the hangers being provided at their upper ends with eccentric-boxes 9 in which the eccentrics 10, carried by rotatable shafts 11, opcrate. The shafts 11 have gear-wheels 12 fixed to them and intermeshing with each other, these Wheels being driven by any suitable form of power connection.

13 is a refuse-receiving well located at the discharge end of the coal-washer and into which communication from the washingtank is provided through the medium of an opening 1, located in a wall of the washingtank, and with which the outlet 6 of the jig 4 is adapted to register in order that the slate or other refuse matter from the coal may be delivered intosaid refuse-receiving well.

13 is a compartment located alongside of the refuse-well and having communication therewith.

14 is a conveyer, preferably of screw type, which is located at the bottom of the refusereceiving well and by which the refuse is conveyed from said well into the compartment 13. The refuse is removed from the compartment 13 by a conveyer (not shown) of any suitable form. The conveyer 14 is operated through means that will now be described.

15 designates a driving-wheel fixed to one of the rotatable jig-operating shafts 11, the wheel being preferably of friction type.

16 is a shaft which is mounted in suitable journal-boxes supported by the frame of the coal-washer. This shaft 16 is provided with an eccentric 17. (See Figs. II, III, and IV.)

18 is a driving-wheel, preferably of friction type, which opposes the driving-wheel 15 and which is mounted on the shaft 16 at the location of the eccentric 17 to provide for said eccentric operating within said Wheel. The wheel 18 has an extended belt-receiving hub 19, which is preferably provided with teeth to form a sprocket-wheel that receives an endless chain belt 20.

21 is a shaft journaled in suitable boxes on the frame of the washer and to which is fixed a belt-receiving wheel 22, on which the belt 20 operates. The shaft 21 also has fixed to it a driving-wheel 23, that receives a belt 24, which leads to a wheel fixed to the shaft of the conveyer 14 and serves to drive said conveyer for refuse-discharging action.

27 designates a lever rockingly supported by a rod 28, suitably attached to the frame of the washer. This lever has fixed to its lower end a plate or pan 29, that is located at the lower end of the coal-delivery chute 3 inorder that the coal delivered from said chute into the jig 4 will constantly strike against said plate or pan before descending into the jig and cause the upper end of the lever to be thrown in a direction toward the delivery-chute.

30 is a pull-rod having its forward end connected at 31 to the upper end of the lever 27.

32 is a cra11k-arm fixed to the shaft 16, which is provided with an eccentric 17 and on which the driving-wheel 18 is mounted. This crank-arm has the pull-rod 30 pivotally connected thereto at 34 is a counterbalance or retracting weight mounted upon the rear end of the pull-rod 30.

In the operation of a coal-washer having my improvement embodied therein when the coal is delivered from the delivery-chute 3 it acts, by striking against the pan or plate 29, to hold the upper end of the lever 27 in a forward position, and this lever constantly eX- erts a pull upon the pullrod 30, as a result of which the cranlcarm 32 is held in a forward position. When said crank-arin is moved forwardly, due to the forward movement of the pull-rod, the shaft 16 is rocked and the eccentric 17 is moved sufficiently to cause it to act against the driving-wheel 1S surrounding it and shift said driving-wheel in a direction toward the opposing driving-wheel 15 on one of the jig-operating shafts, and motion is therefore caused to be transmitted from the jig-operating shaft driving wheel to the first-named wheelviz., the wheel 18. The wheel 18 being put in motion serves to drive the belt 20. Said belt in turn serves to drive the shaft 21, and said shaft drives the conveyer 14 through the medium of the belt 26. Immediately upon the delivery of coal ceasing the pan or plate 29 returns to its normal position, due to the impact of coal against the pan or plate being discontinued. The return of the pan or plate to its normal position is occasioned through the medium of a counterbalance-weight 34, which causes the levers with which it is associated to be tilted and the eccentric 17 to be rotated sufficiently to remove the driving-wheel 18 from engagement with the driving-wheel 15 on the jigoperating shaft to which it is applied, with the result of discontinuing the operation of the refuse-conveyer until delivery of coal is again resumed. Due to the provision of the well 13 of my coal-washer and the fact that said well has communication with the of the washer I am enabled to control the outlet of refuse from said jig and also to prevent dis charge or waste of coal through the refuseoutlet. This is due to the fact that the waste-outlet and the aperture opening into the refuse-well are constantly occupied by refuse, and when the operation of the con veyer 14 ceases the refuse in the jig-outlet and aperture just referred to serves to prevent the eXit of the coal into the refuse-well. It will therefore be seen that at no time is it possible for coal to be dischargedfwith the refuse.
